XTP over AAL 5 for multimedia applications

The emerging of high-speed networks provides the infrastructure for handling a wide set of new applications, covering distributed multimedia cooperative features. The new quality of service provided by these networks as well as the various requirements of these applications raises new architectural and protocol issues and trends to cope with this paradigm. The transport layer is one point of interest because it is the one between processing and communication. Also, AAL type 5 is the most popular ATM adaptation layer today and is available in all ATM products. in this paper, we briefly overview the XTP and AAL 5 key characteristics, then analyse how these two protocols can work together in order to provide the required services to the user's applications.
